Of a narrow elongate form and pitchy colour, sparsely covered 

 with a short light red pile. The antennae are broad, the first 

 joint is square and rectangular, the second is narrower than the 

 third, the rest are equal in width, but the last is as long as three 

 others put together. The head is abruptly angled behind, form- 

 ing a very mai'ked neck. The thorax is narrower than the head 

 and much longer than broad, is coarsely and somewhat rugosely 

 punctured, has the sides a little rounded before the middle and 

 constricted near the base, and has the median line only visible in 

 the somewhat flattened middle part of the back. The external 

 angles of all the tibi^ are acute.

 Long. 6 lin., lat. If lin. 



Piceo-rufus nitidus, capite inter oculos depresso, antennis sub- 

 latis articulo prime subtransverso, thorace subelongato 

 antice angustato dorso punctato canaliculato transversim 

 striolato, elytris thorace latioribus parallelis truncatis sub- 

 tiliter punctatis punctis setigeris, tibiis posticis extus obtuse 

 terminatis.

 I name this species after Mr. Waterhouse of South Australia, 

 to whom I am indebted for many valuable insects from that 

 territory. It in some respects much resembles A. Mastersii, 

 but is of narrower form and redder colour, has the antenna less 

 broad and the thorax coarsely punctured and depressed on the 

 medianjine.

 Long. 3 1 lin.

 prime transverse, 2, 3, 4 gradatim latioribus 5, 6, 7, 8, 9 

 longitudine quinquies latioribus, thorace oblongo subparal- 

 lelo dorso subdepresso medio subtilissime canaliculato, ely- 

 tris apice conjunctim emarginatis, tibiis anticis extus acute 

 intermediis et posticis obtuse terminatis.
